  • Service: Eagle connecting rods and cranks are designed and manufactured to our specifications. Some simply purchase generic products and package in their boxes without having any control or input in production. Eagle uses only certified steel in production of their steel cranks and rods. No shortcuts are taken that might compromise the quality of the finished piece. We use multi-stage heat treating, sonic testing, magna-fluxing, and x-ray to ensure a reliable product. While Eagle may not be the least expensive
  • Selection: Our selection is the most comprehensive in the industry with close to 200 different connecting rods, over 200 crankshafts, and 2400 balanced rotating assemblies. We offer premium forged 4340 crankshafts and H-Beam rods for serious performance applications, and quality cast steel cranks and I-Beam rods for the weekend racer.
  • Traditional I-Beam design with as-forged surface.
  • ARP 8740 capscrew rod bolts for proven reliability.
  • Quality: Unlike some manufacturers, Eagle never compromises quality for the sake of a lower price. We use only the newest, state-of-the art equipment and highly skilled craftsmen to produce every part we sell.
